Why is the unloaded function not working on my Hitachi RCUE200AG1 Chiller?
If the unloaded function isn't working on your Hitachi Chiller, it could be due to: * Trouble with the thermistor. Adjust the setting temperature or replace the thermistor. * Trouble with the solenoid valve. Check the coil in the solenoid valve and check the oil passage for clogging. * Worn unloader mechanism. Check the unloaded system parts in the compressor.
Why is the compressor on my Hitachi RCUE200AG1 Chiller so noisy?
A noisy compressor in your Hitachi Chiller could be due to: * Slugging caused by liquid flooding back to the compressor. Check the superheat of suction gas and keep it in the proper range. * Worn parts. Check for the sound of internal parts. Replace the compressor if necessary.
What causes low discharge pressure in a Hitachi Chiller?
Low discharge pressure in a Hitachi Chiller can be attributed to: * Extremely cold condenser air. Check the ambient temperature. * Insufficient refrigerant charge. Add refrigerant. * Leakage from the compressor discharge valve. Replace the valves or the entire compressor, if required. * Suction pressure is lower than standard. See “ Low Suction Pressure.”
